Director David Lowery discusses his hit film from this year's Sundance Film Festival. Ain't Them Bodies Saints tells the story of a young outlaw couple, Ruth (Rooney Mara) and Bob (Casey Affleck), who are apprehended after a shootout in the Texas hills. Although Ruth wounds an officer, Bob takes the blame. But four years later, Bob escapes from prison and sets out to find Ruth and their daughter, born during his incarceration. Moderated by Chris Hewitt at the Apple Store Regent Street, in London.
